disadvantages of cinahl database
Once optimal recall is achieved, macros are used to translate the search syntaxes between databases, though manual adaptation of the thesaurus terms is still necessary. Stevinson C, Lawlor DA. All searches in this study were developed and executed by W.M.B. 4 and 5. We have not yet gathered enough data to be able to make a full comparison between Embase and Scopus. The median % of unique studies was 9.09 %; while the range had a lowest value of 5.0 % to the highest value of 33.0 %. J Med Libr Assoc. Improvement of precision was calculated as the ratio between the original precision from the searches in all databases and the precision for each database and combination. Sixteen percent of the included references (291 articles) were only found in a single database; Embase produced the most unique references (n=132). Would you like email updates of new search results? 2011;91:1907. 2013;66:10517. Are MEDLINE searches sufficient for systematic reviews and meta-analyses of the diagnostic accuracy of depression screening tools? Can Fam Physician. 8600 Rockville Pike Investigators and information specialists searching for relevant references for a systematic review (SR) are generally advised to search multiple databases and to use additional methods to be able to adequately identify all literature related to the topic of interest [1,2,3,4,5,6]. The three databases were searched for citations on topics selected by three nurse researchers and the results were compared. Case studies may be prospective (in which criteria are established and cases fitting the criteria are included as they become available) or retrospective (in which criteria are established and cases are selected from historical records for inclusion in the study). The calculation is shown in Table5. Films Media Group is the leading source of high-quality video and multimedia for academic, vocational and life-skills content. J Kerman Univ Med Sci. Comparing International Pharmaceutical Abstracts and MEDLINE. A comparative study of clinical end-user and librarian searches. The ratio between number of results per database combination and the total number of results for all databases, The ratio between precision per database combination and the total precision for all databases. The reviews covered a wide variety of disease, none of which was present in more than 12% of the reviews. BMC Med Res Methodol. "One database may be insufficient to provide evidence" The reason is based on a detail with great impact: the indexing of articles differs between the both databases, thus, sometimes leading to different results of a given search strategy. disadvantages of cinahl database. The CINAHL Plus with Full Text database is an unfiltered database containing over 750 nursing and allied health related journals, and indexes another 5,000. using CINAHL alone. Bramer WM, Giustini D, Kramer BM, Anderson PF. Google Scholar. The contribution of databases to the results of systematic reviews: a cross-sectional study. [26] found that Cochrane CENTRAL included 95% of all RCTs included in the reviews investigated. We copied from the MeSH tree the top MeSH term directly below the disease category or, in to case of the intervention, directly below the therapeutics MeSH term. Of the combinations of two databases, Embase and MEDLINE had the best results (92.8%). HHS Vulnerability Disclosure, Help It is likely caused by difference in thesaurus terms that were added, but further analysis would be required to determine reasons for not finding the MEDLINE records in Embase. PubMedGoogle Scholar. It therefore finds articles in which the topic of research is not mentioned in title, abstract, or thesaurus terms, but where the concepts are only discussed in the full text. ERIC for example serves as the most comprehensive source of information containing more than 500,000 documents and journal articles from all areas of education. Whether Embase and Web of Science can be replaced by Scopus remains uncertain. A total of 292 (17%) references were found by only one database. 2006 Jul;59(7):710-4. doi: 10.1016/j.jclinepi.2005.09.013. CINAHL provided the majority of relevant articles for the second search, on computers and privacy, but inclusion of MEDLINE and EMBASE enhanced retrieval somewhat. Quick Answer: What are Boolean operators? J Clin Epidemiol. Wilkins T, Gillies RA, Davies K. EMBASE versus MEDLINE for family medicine searches: can MEDLINE searches find the forest or a tree? 2016;5:39. 2005;58:86773. The other study from the Journal of Advanced Nursing is indexed in MEDLINE and Embase but was only retrieved because of the addition of KeyWords Plus in Web of Science. According to our data, PubMeds as supplied by publisher subset retrieved 12 unique included references, and it was the most important addition in terms of relevant references to the four major databases. To ensure adequate performance in searches (i.e., recall, precision, and number needed to read), we find that literature searches for a systematic review should, at minimum, be performed in the combination of the following four databases: Embase, MEDLINE (including Epub ahead of print), Web of Science Core Collection, and Google Scholar. Asterisk indicates that the recall of all databases has been calculated over all included references. Size Unauthorized use of these marks is strictly prohibited. A recent paper tried to find an acceptable number needed to read for adding an additional database; sadly, however, no true conclusion could be drawn [20]. PubMed The Cochrane Handbook recommends searching MEDLINE, Cochrane CENTRAL, and Embase for systematic reviews of RCTs. Although we did not use these special topic databases in all of our reviews, given the low number of reviews where these databases added relevant references, and observing the special topics of those reviews, we suggest that these subject databases will only add value if the topic is related to the topic of the database. The information specialists of Erasmus MC developed an efficient method that helps them perform searches in many databases in a much shorter time than other methods. To our surprise, Cochrane CENTRAL did not identify any unique included studies that had not been retrieved by the other databases, not even for the five reviews focusing entirely on RCTs. LearningExpress Library features nearly 1,000 online tutorials, practice tests, and eBooks to help patrons of all ages. Aagaard T, Lund H, Juhl C. Optimizing literature search in systematic reviewsare MEDLINE, EMBASE and CENTRAL enough for identifying effect studies within the area of musculoskeletal disorders? Depending on the goal of the search, different measures may be optimized. Beckles Z, Glover S, Ashe J, Stockton S, Boynton J, Lai R, Alderson P. Searching CINAHL did not add value to clinical questions posed in NICE guidelines. Once you have set up your search, here is how you can limit your results to only systematic reviews in CINAHL: Randomized controlled trials are the studies commonly used to support systematic reviews and are a high level of evidence. [10] and van Enst et al. See Fig. 11 reviews, where we were able to recheck all the databases used by the original review authors, had included a study that was uniquely identified from the CINAHL database. New candidate terms are added to the basic search and evaluated. Halladay CW, Trikalinos TA, Schmid IT, Schmid CH, Dahabreh IJ. They are usually one of the easiest study types to find in any nursing or medical database. PubMed Central In our analyses, we combined the results from MEDLINE in Ovid and PubMed (the subset as supplied by publisher) into one database labeled MEDLINE. Using that combination, 93% of the systematic reviews in our study obtained levels of recall that could be considered acceptable (>95%). The interventions were mostly from the chemicals and drugs category, or surgical procedures. To categorize the types of patient/population and intervention, we identified broad MeSH terms relating to the most important disease and intervention discussed in the article. Table3 displays the number of unique results retrieved for each single database. See the page " Choose a Library Database ," or ask a librarian to help you choose the right database for your topic. The combination of Embase, MEDLINE, Web of Science Core Collection, and Google Scholar performed best, achieving an overall recall of 98.3 and 100% recall in 72% of systematic reviews. The search on substance abuse in pregnancy, not restricted to nursing literature, retrieved better results when searching both MEDLINE and EMBASE. Once validated and certified for inclusion, these OA journals are treated with high-quality subject indexing and sophisticated, precise/accurate full-text linking. Other specialized databases, such as CINAHL or PsycINFO, add unique references to some reviews where the topic of the review is related to the focus of the database. For 55 reviews, we determined the domain. Embase retrieved the most unique included references, followed by MEDLINE, Web of Science, and Google Scholar. f~C>j)Kx8t>qi0@fWT. Percentage of systematic reviews for which a certain database combination reached a certain recall. Using the prospectively recorded results and the studies included in the publications, we calculated recall, precision, and number needed to read for single databases and databases in combination. The references to these reviews can be found in Additional file 1. Published reviews were included if the search strategies and results had been documented at the time of the last update and if, at minimum, the databases Embase, MEDLINE, Cochrane CENTRAL, Web of Science, and Google Scholar had been used in the review. Fifty-one of these journals are UK publications. We analyzed whether the added value of Web of Science and Google Scholar was dependent of the domain of the review. There are disadvantages to using multiple databases. In addition, Michaleff et al. Optimal database combinations for literature searches in systematic reviews: a prospective exploratory study, https://doi.org/10.1186/s13643-017-0644-y, http://creativecommons.org/licenses/by/4.0/, http://creativecommons.org/publicdomain/zero/1.0/. <> We recommend that, regardless of their topic, searches for biomedical systematic reviews should combine Embase, MEDLINE (including electronic publications ahead of print), Web of Science (Core Collection), and Google Scholar (the 200 first relevant references) at minimum. Some concluded that searching only one database can be sufficient as searching other databases has no effect on the outcome [16, 17]. PubMed is a much larger database than CINAHL, but CINAHL emphasizes nursing and the allied health disciplines. To learn more about Boolean operators, please see this Quick Answer: Here is an example of how to put together a complex search in CINAHL: Note: If you have not already logged in to the Library databases, you will be prompted to log in with your myWalden Portal user name and password. This database also offers indexing and abstracts for more than 10,100 journals and a total of 10,600 publications including monographs, reports, conference proceedings, etc. To identify whether our searches had found the included references, and if so, from which database(s) that citation was retrieved, each included reference was located in the original corresponding EndNote library using the first author name combined with the publication year as a search term for each specific relevant publication. For example, around a third of the reviews (37%) relied on the combination of MEDLINE and Embase. In the case of a clinical question, precision is most important, as a practicing clinician does not have a lot of time to read through many articles in a clinical setting. This Spanish language database contains full text for 130 peer-reviewed medical journals in native Spanish. Ws"30z@+RY{"+NTzXnnf.ote{X-C.!0rxY_K+LSA12"fDAKJtk/FQS. Transcript. Careers.

Eighty-one journals are uniquely indexed in BNI compared with all versions of CINAHL. Syst Rev 6, 245 (2017). Of all reviews in which we searched CINAHL and PsycINFO, respectively, for 6 and 9% of the reviews, unique references were found. j 'o Disadvantages of Databases 1. 'VI/:NAf] N1b v4Fl8KTs cinQ Because these studies based on retrospective analysis of database coverage do not account for the searchers abilities, the actual findings from the searches performed, and the indexing for particular articles, their conclusions lack immediate translatability into practice. iOm3w]9`V>@X(xF$u,mA5US{^2w" `15p3SCzSM2w+!

Prior research on database importance for systematic reviews has looked primarily at whether included references could have theoretically been found in a certain database, but most have been unable to ascertain whether the researchers actually found the articles in those databases [10, 12, 16, 17, 26]. We aimed to determine the optimal combination of databases needed to conduct efficient searches in systematic reviews and whether the current practice in published reviews is appropriate. 0_!g3SR}W/galG/g)Wz37;467WfW_E\wf_Q"#H3)j\]'gr[ ~dFq @Xj7yfC pOYAnaKruN" VI$wkD F\+ Fd7[)g `xBI@Oj endobj Documentaries on the full spectrum of diseases and disorders; titles on human anatomy and physiology; investigations into public health issues; programming on nutrition and wellness; instructional films on health care and treatment; primers on. Conclusion Int J Technol Assess Health Care. The third key database we identified in this research, Web of Science, is only mentioned as a citation index in the Cochrane Handbook, not as a bibliographic database. l1FcqL@Bk>>T 2014;67:11929. volume6, Articlenumber:245 (2017) The X-axis represents the percentage of reviews for which a specific combination of databases, as shown on the y-axis, reached a certain recall (represented with bar colors). Is the coverage of Google Scholar enough to be used alone for systematic reviews. It is therefore important to search MEDLINE including the Epub Ahead of Print, In-Process, and Other Non-Indexed Citations references. 4 0 obj 2015 Jun 26;4:82. doi: 10.1186/s13643-015-0074-7. If an included reference was not found in the EndNote file, we presumed the authors used an alternative method of identifying the reference (e.g., examining cited references, contacting prominent authors, or searching gray literature), and we did not include it in our analysis. Terms and Conditions, PubMed 2008;14:4014. We documented the department of the first author. Ross-White A, Godfrey C. Is there an optimum number needed to retrieve to justify inclusion of a database in a systematic review search?
